MACHINE FOR WELDING CALKS TO HORSESHOES.

SPECIFICATION forming part of Letters Patent No. 440,372, dated November11, 1890.

Application filed September 1, 1390. Serial N0.363,703. (N0 model.)

To all whom it may concern.-

Beit known that I, CHARLES E. SOHROEDER, a citizen of the United States,residing at Crown Point, in the county of Lake and State of Indiana,have invented a certain new and useful Improvement in Machines forW'elding Oalks to Horseshoes, of which the following is a specifiation.

My invention relates to improvements in machines for welding calks tohorseshoes and analogous purposes; and it consists in certainpeculiarities of the construction and novel arrangement of the variousparts thereof, as will be hereinafter more fully set forth, andspecifically claimed.

The objects of my invention are to afford a machine for the above-namedpurpose which shall be inexpensive, simple in construction andoperation, strong and durable, and more effective and rapid in its workthan the ordinary manner of welding.

In order to enable others skilled in the art to which my inventionpertains to make and use the same, I will now proceed to describe it,referring to the accompanying drawings, in which- Figure 1 is aplan viewof my machine. Fig. 2 is a view in side elevation. Fig. 3 is a verticalsectional View taken on line a: 00 of Fig. 2 and looking in thedirection indicated by the arrows. Fig. 4 is a longitudinal sectionalview showing the interior mechanism and the shoein place to be operatedon. Figs. 5, 6, and 7 are detail views of the operating-lever and itsfulcrum. Fig. 8 is a rear end view of the machine. Fig. 9 is aperspective view of one of the die-plates, and Fig. 10 is a view of oneof the calk-pieces.

Similar letters refer to corresponding parts throughout the differentviews of the drawlngs.

A represents the main frame of my machine, which is made of suitablesize and material, and, as shown in Fig. 2 of the drawings, may bebolted to a proper supporting device by means of bolts passed throughthe openings a thereof. In constructing this frame I preferably make itof two plates A A which are similar in size and every respect, exceptthat the plate A is provided with bearings for certain levers, whichwill be presently explained. Between these two plates, and at the upperportion of the front end thereof, is firmly secured by meansofscrew-bolts a, or otherwise a block or anvil B of solid metal ormaterial, which is provided near its upper inner portion with aprojection a which extends horizontally across the anvil B and isadapted to engage with a suitable groove in the die or dies 0, as willbe more definitely explained.

The plates A A are cut away near their upper central portion, as at b,to readily admit the insertion and the extraction of the shoe D and die0, as is clearly seen by reference to Figs. 2 and 4 of the drawings.

The inner surfaces of the upper rear portion of the plates A A areprovided with in wardly-projecting pieces 0 c, which form a track orguideway for the plunger E, which is made of rectangular shape andformed at its front end solid, with a flat face to be presented to theside of the die. The rear end of this plunger is bifurcated, as seen inFig. 4, which permits of it being easily adjusted to or from the die toaccommodate shoes of different thicknesses. In the bottom of the solidportion of the plunger and near the front end of the fork is formed arecess, (not shown in the drawings,) into which the free end of thespring F is inserted, the said spring being firmly secured at its lowerend to a bolt 0, which assists in securing the plates A A together, andthe spring serves to retract the plunger after it has been thrownforward by the operating-lever G, which is formed at its lower end withan eccentric d, which is fulcrumed on an eccentric-pin H, which pin hasits bearings in the upper rear portion of the plates A A as shown in thedrawings.

At a suitable point on the lever G is adj ustably secured, by means of aset-screw e or otherwise, a weight I, which accelerates the fall of thelever, and thereby adds force to the blow of the plunger, as will bereadily understood.

To the outside of the plate A a springactuated lever K is fulcrumed, asat e, and has on its upper end a pin 6 loosely secured thereto, whichpin passes through a hole in the plate A and into a recess a of theeccentric on the lever G, thus holding the lever in the position shownin Figs. 2 and 4. When it is desired to release the lever G, the lowerend of the lever K is pressed toward the plate, which operationwithdraws the pin (2 from its socket, and thus allows the lever todescend. When the lever G is raised to the position shown in Fig. 2, thespring m, which is secured at one end to the plate A and has its freeend resting against the inner side of the lever K, forces the pin 6 backinto the socket, as will be readily understood. The eccentric H hasitsbearings in the side pieces A A of the main frame and projects slightlythrough the piece A to which projecting end a handle or lever L isrigidly secured by means of a set-screw or otherwise to operate theeccentric when it is desired. It will be understood that the eccentric Hserves the twofold purpose of an axis or journal for the lever G and toadjust the plunger E to accommodate shoes of different thicknesses, forby turning the eccentric H slightly or half-way round, as shown bydotted lines in Fig. 5, as at n, the plunger E will be forcedcorrespondingly forward, as indicated by the dotted lines in the samefigure. In Fig. 9 I have shown a detail view of a die-plate having aseries of recesses 0 of various sizes and forms, into which thecalk-piece is forced and formed. As shown in the drawings, I form theserecesses with an inward bevel, which shape corresponds to the beveled orsharpened form of the calk when it is being welded to the shoe. It willtherefore be seen and understood that I sharpen the calk at the sametime and by the same operation that I employ in welding it to the shoe.It is sometimes desired to form the shoe with a projection r on the topof the toe of the shoe op-' posite the toe-calk, and in order to do thisI provide the upper portion of the front end of the plunger E with adepression 19 of suitable size and form. When it is not desired to formthe shoe as above described, the depression 19 may be plugged by asuitable piece secured therein.

To form the heel-calks on the shoe, the shoe is heated to the properdegree and placed and held against the plate 0 by the plunger, when theends may be bent over the die-plate by a stroke or two of a hammer.

Fig. 10 represents an ordinary steel calk as it appears before beingattached to the shoe.

The operation of my device is simple, and as follows: The die-plate isplaced in the frame, as shown in the drawings, and held in place by theprojection a in the groove of the plate. The calk is attached to theshoe by driving the prong thereof into the shoe when both are heated tothe proper degree. The calk is now placed in one of the recesses 0 andthe lever K pressed to the frame, which liberates the lever G, whichdescends and throws the plunger forward with great force, thus weldingand shaping the calk, as has been before explained.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is-

1 In a machine for welding calks to horse shoes, the combination of themain frame A, having the anvil B, provided with the projection a tosecure the die C, with the die having a number of recesses 0, theplunger E, the lever G, having the adjustable weight I, and eccentricd,'journaled on the eccentric H, all constructed, arranged, andoperating substantially as shown and described, and for the purpose setforth.

2. In a machine for welding calks to horseshoes, the combination of theframe A, having the anvil B, having means for supporting and retainingthe die 0, and a track 0 for the plunger E, with the plunger having oneend bifurcated and the other end solid, the lever G, having theadjustable weight I, eccentric d, having the recess 6 and fulcrumed onthe eccentric H, the eccentric H, having the handle L, and the lever K,fulcrumed to the plate A and having the pin 6 to engage the eccentric d,all constructed, arranged, and operating substantially as shown anddescribed, and for the purpose set forth.

3. In a machine for welding calks to horse-- shoes, the combination ofthe main frame A, having the anvil B, having means for supporting andsecuring the die 0, a track for the plunger E, with the plunger havingone end bifurcated and the other solid and provided with the recess 10and spring F, the lever G, having the adjustable weight I, the eccentricd, having the recess 6 and fulcrumed on the eccentric H, the eccentricH, having the handle L, the spring-actuated lever K, having the pin eand the die-plate 0, having a number of inwardly-beveled recesses, sub-.stantially as set forth.

In Witness whereof I have hereunto set my hand and affixed my seal this27th day of August, 1890.
